CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. application Ser. No.12/391,599 filed Feb. 24, 2009 which claims the benefit of U.S.Provisional Application No. 61/031,172, filed Feb. 25, 2008.

FIELD OF THE INVENTION

The present invention relates to hair care compositions for delivering aconditioning benefit, comprising sucrose polyesters.

BACKGROUND OF THE INVENTION

Human hair becomes dry and/or damaged due to the surroundingenvironment, styling, drying, and/or coloring or otherwise chemicallytreating the hair.

A variety of approaches have been developed to condition the hair. Acommon method of providing conditioning benefit is through the use ofhair care compositions containing conditioning agents such as cationicsurfactants and polymers, high melting point fatty compounds, lowmelting point oils, silicone compounds, and mixtures thereof. Siliconesare often used as a conditioning active for a number of hair carecompositions. However, the rising costs, the inefficient conditioning ofdamaged hair, and the petroleum based nature of silicone has minimizedits desirability as a conditioning active.

Based on the foregoing, there is a need for a conditioning active whichcan provide conditioning benefits to hair which can replace, or be usedin combination with silicone, or other conditioning active, to maximizethe conditioning activity of a hair care composition. Additionally,there is a need to find a conditioning active which can deliver aconditioning benefit to damaged hair, which has previously beendifficult to condition using traditional conditioning actives. Finally,there is a need to find a conditioning active which can be derived froma natural source, thereby providing a conditioning active derived from arenewable resource.

None of the existing art provides all of the advantages and benefits ofthe present invention.

I. Sucrose Polyesters

The hair care compositions of the present invention comprise one or moretypes of sucrose polyesters (also referred to herein as “Sefose”).Sucrose polyesters are derived from a natural resource and therefore,the use of sucrose polyesters as the conditioning active can result in apositive environmental impact.

Sucrose polyesters are polyester materials, having multiple substitutionpositions around the sucrose backbone coupled with the chainlength,saturation, and derivation variables of the fatty chains. The Sucrosepolyesters display both a range of esterification and saturation asshown in FIG. 1.

The sucrose polyester of the present invention have an esterification(“IBAR”) of greater than about 5. In one embodiment the sucrosepolyester may have an IBAR of from about 5 to about 8. In anotherembodiment the sucrose polyester has an IBAR of about 5-7, and inanother embodiment the sucrose polyester has an IBAR of about 6. In yetanother embodiment the sucrose polyester has an IBAR of about 8. As thesucrose polyesters are derived from a natural resource, a distributionin the IBAR and chain length may exist. For example a sucrose polyesterhaving an IBAR of 6, may contain a mixture of mostly IBAR of about 6,with some IBAR of about 5 and some IBAR of about 7. Additionally, thesucrose polyester of the present invention may have a saturation oriodine value (“IV”) of about 3 to about 70. In another embodiment thesucrose polyester of the present invention may have an IV of about 3. Inyet another embodiment the sucrose polyester of the present inventionmay have an IV of about 40. The sucrose polyesters of the presentinvention may have a melting point greater than about 30° C. Further,the sucrose polyesters of the present invention has a chain length ofabout C12 to C14, and may comprise some C16, for the sucrose polyestershaving an IBAR of about 5 to about 7. For the sucrose polyesters havingan IBAR of about 8, the chain length is about C16 to C18.

In yet another embodiment the conditioning active can comprise a blendof more than one sucrose polyester. This sucrose polyester blend cancomprise two or more sucrose polyesters, wherein at least one sucrosepolyester has a melting point greater than about 30° C., an IBAR greaterthan about 5, an IV of about 3 to about 70, and at least one sucrosepolyester has an IBAR between about 1 and about 8, and an IV betweenabout 1 and about 135, and wherein the sucrose polyester blend has anIBAR of at least 5 and an IV of about 1 and about 135. In one embodimentthe sucrose polyester blend can be at a ratio of about 1:1, in anotherembodiment the sucrose polyester blend can be at a ratio of about 1:2,in yet another embodiment the sucrose polyester can be at a ratio ofabout 1:3, in yet another embodiment the sucrose polyester can be at aratio of about 1:5, in yet another embodiment the sucrose polyester canbe at a ratio of about 3:4, and in yet another embodiment the sucrosepolyester can be at a ratio of about 3:10 of the sucrose polyesterhaving a melting point greater than about 30° C., an IBAR greater thanabout 5, an IV of about 3 to about 70 to the sucrose polyester having anIBAR between about 1 and about 8, and an IV between about 1 and about135. In one embodiment the sucrose polyester blends can have a G′ valueof from about 0.22 Pa to about 10,030 Pa at 0.01 Hz. Additionally, inone embodiment the sucrose polyester blends can have a G″ value of fromabout 0.83 Pa to about 23,960 at about 0.01 Hz.

Table 1 reports the average values of G′ and G″ from 0.01 Hz, up to 100Hz, for varying blends of a sucrose polyester having a melting pointgreater than about 30° C., an IBAR greater than about 5, an IV of about3 to about 70 (Sefose 1618H, P&G Chemicals) with a sucrose polyesterhaving an IBAR between about 1 and about 8, and an IV between about 1and about 135 (Sefose 1618U, P&G Chemicals). The blends are prepared byplacing the amounts and types of sucrose polyesters, at the specifiedratio, in a stainless steel beaker which is heated in a water bath atabout 75° C. At this temperature any solid sucrose polyester present inthe blend melted and is intimately mixed with all other sucrosepolyester to create a homogenous mixture. After this, the beaker isremoved from the bath and allowed to cool at room temperature. Samplesfrom these blends are transferred to the rheometer for G′ and G″measurements.

Examples of sucrose polyesters suitable for use in the present inventioninclude, but are not limited to, Sefose 1618H, Sefose 2275C, 1618S allavailable from The Procter and Gamble Co. of Cincinnati, Ohio.

The following data (shown in Table 2) shows that sucrose polyestershaving the abovementioned characteristics deliver dry combing benefits,which correlates to conditioning, that exceed the dry combing benefitsof sucrose polyesters that do not have the above-mentionedcharacteristics. For example Sefose C1618 IB6 IV85, has lower drycombing benefits than Sefose C1618 IB6 IV40 and IV 56, and Sefose C1618IB6 IV3. Additionally, Sefose C1618 IB8 IV 135, and Sefose C1618 IB8IV85 have lower dry combing benefits than Sefose C1618 IB8 IV38, SefoseC2275 IB8 IV5 and Sefose C1618 IB8 IV3.

In addition to use in hair care compositions, sucrose polyesters of thepresent invention may be beneficial as a conditioning agent in personalcare compositions, in particular personal cleansing compositions such asa body wash.

Conditioning Benefit

Silicone does not traditionally condition damaged or low lift hair asefficiently as silicone conditions undamaged hair. Low lift hairincludes hair that has been exposed to bleaching or other coloringagents. Hair care formulations, in particular shampoo formulations,comprising the sucrose polyester of the present invention work wellalone or in combination with silicone conditioning actives to deliverimproved dry combing benefits to damaged or low lift hair. Addingsilicone, and in particular small particle silicone, adds to the combingbenefit. The silicone and sefose do not counteract each other. Thefollowing Tables 3-4 indicate that Sefose in a clarifying shampoo basehas better dry combing benefit (which correlates to a conditioningbenefit) than a clarifying shampoo alone, for both low lift and virginbrown hair. Additionally, Tables 3-4 below indicate that Sefose combinedwith small particle silicone in a clarifying shampoo base is nearlyequivalent in dry combing benefit to Clarifying/Si Conditioner which isa conditioner for low lift hair, and is equivalent in dry combingbenefit to Clarifying/Si Conditioner for virgin brown hair. See Tables5-7 for formulations described in Tables 3-4.

If a water insoluble co-surfactant isdesired the surfactant and water mixture can be heated to a suitabletemperature to facilitate its incorporation. If a rheology modifier isdesired it can be added to the surfactant mixture prior the finishingstep.

In the case of conditioning shampoos, typically the surfactant paste iscombined with the co-surfactant as above and diluted with water to atarget level commensurate to achieving the final activity. Rheologymodifiers can be added at this point followed by conditioning agents,e.g. sucrose polyesters, silicones or silicone emulsions or other oils,cationic polymers from polymer premixes, perfumes, pearlizing agents oropacifiers, perfumes, and preservatives. Appropriate mixing steps toinsure homogeneity are used as needed. The product is finished by theaddition of pH control agents, hydrotropes, and salts to the desiredphysical properties.

No. 61/011,631filed Jan. 18, 2008.

Method of Making Compact Formulations

In order to get to the surfactant active levels for the products thatuse ⅓ the typical shampoo weight or volume level there is a need to useone or more of the components that are derived from higher activitylamellar phase pastes. These materials can include, but are not limitedto, SLE(1)S, C11E(1)S, C13-15 paraffin sulfonate, as flowable fluids.Higher activity isotropic pastes of C11S (35%) and SLS containing anenriched level of C10 (38%) can be made to facilitate these formulationsas well. In a typical procedure the isotropic paste can be combined withthe co-surfactant, preservatives, and the desired quantity of lamellarphase paste. This can be mixed on a Flak Tek speed mixer until uniform.Pearlizer dispersion (EGDS), cationic polymer, and perfume are added andmixed again until a uniform mixture is achieved. Finally, surcrosepolyesters, silicone emulsion, additional preservatives and pH controlagents are mixed in with more gentle agitation to achieve the desiredfinal product mixture.

Test Methods

G′ and G″ Test Method

This method provides a G′ and G″ value for a given sucrose polyesterblend composition. Each blend is carefully transferred to a rheometerplate while avoiding applying vigorous shear to each blend composition.

A suitable rheometer for use in the present method is the Haake RS-150RheoStress Rheometer interfaced with a computer having suitable softwarethat provides data recordation and analysis. The test is performed attemperature of 35° C. and the equilibration time is 3 minute. Therheometer is configured with a 35 mm diameter, 4 degree steel cone at agap setting to the plate of 140 μm as measured from the center of thecone. The angular frequency is applied, starting at 0.01 Hz, where G′and G″ are measured three times and the average of G′ and G″ arerecorded by the software. Similarly, these measurements are repeated ateach decade after 0.01 Hz and up to 100 Hz. All measurements wereperformed at a constant stress of 1 Pa.

Wet and Dry Conditioning Test Method

This test method is designed to allow for a subjective evaluation of thebasic performance of conditioning shampoos for both wet combing and drycombing efficacy. The control treatments are a clarifying shampoo thatemploys only surfactants and has no conditioning materials present andthis same shampoo used in the washing process followed by theapplication of a mid-range hair conditioner. These treatments allow foreasy differentiation of performance of a set prototype conditioningshampoos. In a typical test 3 to 5 separate formulations can be assessedfor their performance. The substrate is virgin brown hair obtainablefrom a variety of sources that is screened to insure uniformity and lackof meaningful surface damage.

Treatment Procedure

Five 4 gram, 8 inch length switches are combined in a hair switchholder, wet for ten seconds with manipulation with water at 40 C andtypical hardness (9-10 gpg) to insure complete and even wetting. Theswitch is deliquored lightly and product is applied uniformly over thelength of the combined switches from one inch below the holder towardsthe end at a level of 0.1 g product per one gram of dry hair (0.1 g/g ofhair or 2 g for 20 g hair). For more concentrated prototypes the usagelevel is reduced to 0.05 g/g of hair. The switch combo is lathered by arubbing motion typical of that used by consumers for 30 seconds andrinsed with water flowing at 1.5 gal/min at 40 C (with the hair beingmanipulated) to insure completeness for 30 seconds. This step isrepeated. On the switch combo where conditioner is applied, it isapplied in the same way as shampoo above, manipulated throughout theswitch combo and rinsed thoroughly with manipulation. The switches aredeliquored lightly, separated from each other, hung on a rack so thatthey are not in contact and detangled with a wide tooth comb.

Grading Procedures

For wet combing evaluations using trained graders, the switches areseparated on the rack into the five sets with one switch from eachtreatment included in the grading set. Only two combing evaluations areperformed on each switch. The graders are asked to compare thetreatments by combing with a narrow tooth nylon comb typical of thoseused by consumers and rate the ease/difficulty on a zero to ten scale.Ten separate evaluations are collected and the results analyzed by astatistical analysis package for establishing statistical significance.Control charting is regularly used to insure that the low and highcontrols separate into their regular domains. Statistical significancein differences between treatments is determined using Statgraphics Plus5.1. All conditioning prototypes must be more than two LSDs above theclarifying control to be viewed as acceptable.

For dry combing evaluations, the switches from above are moved into acontrolled temperature and humidity room (72 F/50% RH) and allowed todry overnight. They remain separated as above and panelists arerequested to evaluate dry conditioning performance by making threeassessments; dry combing ease of the middle of the switch, dry combingease of the tips, and a tactile assessment of tip feel. The same tenpoint scale is used for these comparisons. Again, only two panelistsmake an assessment of each switch set. Statistical analysis to separatedifferences is done using the same method as above.
